Description
Verfahren zur Darstellung von Ergotaminforniiat. Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Darstellung des bisher noch unbekannten Ergotaminformiates. Als Ausgangsmaterial kann man sowohl die reine Base, z. B. ihre Kristallisation aus wasserhal tigem Aceton, wie sie in Patent Nr. 86321 erwähnt ist, oder ein ergotaminreiches Al- kaloidrohpro,dukt verwenden und in letzterem Fall die Salzbildung zur Abtrennung des Er- gotamins von Begleitstoffen verwenden.
Das Verfahren zur Darstellung von Ergo- taminformiat beruht darauf, dass man auf das Alkaloid eine .ausreichende Menge von Ameisensäure nach Art der Salzbildung ein wirken lässt.
Zur Darstellung von Ergotaminformiat in fester kristallisierter Form löst m.a.n die freie Base zweckmässig in mit Wasser misch baren, indifferenten, organischen Lösungs mitteln, wie Alkohol oder Holzgeist auf und fügt hierauf die Ameisensäure zu, worauf die kristallinische Ausscheidung von Ergotamin- formiat einsetzt, oder man fällt das Salz aus einer Lösung des Ergotamins in mit Wasser nicht mischbaren organischen Lösungsmitteln, wie Äther, Chloroform, Benzol, indem man vorsichtig verdünnte Ameisensäure so lange zusetzt, als eine Fällung entsteht.
Man kri stallisiert darauf die abfiltrierte amorphe Fällung aus einem geeigneten Lösungsmittel, z. B. Holzgeist. Ergotaminformiat bildet schöne Kristallisationsverbin.dungen mit or ganischen Lösungsmitteln, z. B. Methyl- und Athylalkohol.
Zur Darstellung von Ergotaminformiat in wässerigen Lösungen, sowohl reinen als auch solchen, denen Konservierungsmittel, wie Al kohol und Glyzerin, zugesetzt sind, fügt man dem Lösungsmittel die ausreichende Menge Ameisensäure: zu und versetzt die so ver dünnte Säure mit einer konzentrierten Lö sung .der Ergotaminbase in einem organischen Lösungsmittel, z. B. Alkohol.
Wie die freie Base, so erleiden auch Er- gotaminformiat und seine Lösungen nament lich am Licht durch Luftsauerstoff o-,-,y:da- tive Veränderungen unter Gelb- und Braun färbung.
Man vermeidet dieselben, indem man bei der Herstellung und bei der Aufbewah rung von Ergotaminformiat und seiner Lö sungen, insbesondere beim Bereiten und Ab füllen von Injektionslösungen, unter Verwen-

Process for the preparation of ergotamine form. The present invention relates to a method for the preparation of the previously unknown ergotamine formate. The starting material can be either the pure base, e.g. B. their crystallization from water-containing acetone, as mentioned in patent no. 86321, or use an ergotamine-rich alkaloid raw product and in the latter case use the salt formation to separate the ergotamine from accompanying substances.
The process for the preparation of ergotamine formate is based on allowing a sufficient amount of formic acid to act on the alkaloid in the manner of salt formation.
To prepare ergotamine formate in solid crystallized form, the free base is expediently dissolved in water-miscible, inert, organic solvents, such as alcohol or wood spirit, and the formic acid is then added, whereupon the crystalline precipitation of ergotamine formate begins, or one the salt is precipitated from a solution of ergotamine in water-immiscible organic solvents, such as ether, chloroform, benzene, by carefully adding dilute formic acid as long as a precipitate is formed.
One kri installed thereupon the filtered amorphous precipitate from a suitable solvent, eg. B. Wood Spirit. Ergotamine formate forms beautiful crystallization compounds with organic solvents such. B. methyl and ethyl alcohol.
To prepare ergotamine formate in aqueous solutions, both pure and those to which preservatives such as alcohol and glycerine have been added, a sufficient amount of formic acid is added to the solvent and a concentrated solution is added to the diluted acid Ergotamine base in an organic solvent, e.g. B. Alcohol.
Like the free base, ergotamine formate and its solutions also undergo o -, -, y: dative changes with yellow and brown coloration when exposed to light due to atmospheric oxygen.
The same can be avoided by using in the production and storage of ergotamine formate and its solutions, in particular in the preparation and filling of injection solutions,
